I haven’t gotten to Bleak House, yet, but find I have to read Dickens with certain level of focus, and there are often so many characters that I had to reread to memorize them and picture them in my mind, for instance the party of friends we meet in The Pickwick Papers or the diverse set of people and locations in the first few chapters of A Tale of Two Cities - it’s the use of in media res maybe contributing to my off balance (and this was a book I already read once a long time ago).
